HYIEOU Sliding Window Locks with Key — 6-Set Aluminum Alloy, Adjustable No-Drill Fit for Horizontal & Vertical Tracks

HYIEOU Sliding Window Locks are adjustable, key-secured safety devices designed to limit how far a sliding window opens, helping prevent falls while allowing controlled ventilation.

These six aluminum-alloy locks come with a vertical heart key and are built to fit common sliding window tracks. They clamp into place without drilling and can be set to fully secure a closed window or stop it at a smaller opening for airflow. Made for both horizontal and vertical sliding windows, the locks are corrosion-resistant and intended for long-term use in homes, apartments, offices, and rental properties.

How do these locks fit my window tracks?

The locks are designed to engage with a range of standard sliding window track profiles. Before ordering, measure your track: the height must exceed 0.48 inches and the track width must be under 0.61 inches. This ensures the clamp and washer sit properly without slipping.

• Required track height: > 0.48 inches (about 12 mm)
• Maximum track width: < 0.61 inches (about 15.5 mm)
• Works on both side and center tracks of sliding windows
• Suitable for horizontal and vertical sliding types

What level of protection and adjustment do they provide?

Each lock lets you choose between fully locking the window closed or stopping it at a narrower opening to allow safe ventilation. The keyed mechanism prevents unauthorized opening, while the adjustable clamp positions let you tailor the gap to your comfort and safety needs.

• Key-secured locking for child and pet safety
• Multiple stop positions for controlled ventilation
• Reduces risk of falls from windows without blocking airflow
• Durable aluminum alloy resists bending or deformation

How do I install the HYIEOU sliding window locks?

Installation takes only a few minutes and requires no drilling or special tools. The package includes plastic washers to protect the window track and screws to secure the clamp; simply position, add the washer, and tighten.

• Step 1: Place the lock where you want to limit the opening
• Step 2: Insert the plastic washer to prevent scratches
• Step 3: Tighten the screw to clamp the lock in place
• Reversible key fits side or center track configurations

Will these locks hold up over time and in different rooms?

The locks use an aluminum alloy body designed to withstand repeated use without deforming. Their construction makes them suitable for interior and exterior-facing windows, including bedrooms, living rooms, and rental units where non-invasive installation is important.

• Rust-resistant material for long service life
• Compact profile that won’t obstruct curtains or blinds
• Non-drilling mounting preserves window integrity for renters
• Works well in homes, offices, apartments, and daycare settings

Who is this for: HYIEOU sliding window locks are made for caregivers, parents, pet owners, landlords, and anyone who wants to limit window openings without permanent modifications. If you need an adjustable, key-secured solution to prevent accidental falls while keeping fresh air flowing, these locks are designed to be a simple, reusable option that fits most standard sliding tracks.
